Confirmed here too. Seems like they have their defaults the wrong way round, but now I've changed it I'm seeing framerates way beyond anything ever achieved with plib. It looks like "Release" mode includes -O3 optimisation. You'll only need to play with the compiler flags if you want any extra architecture specific optimisations (probably best avoided for anyone building packages). -- Jon Stockill [EMAIL PROTECTED] - This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.

If you read the questions when using 'cmake -i .' one of them is what type of build to do: ...Debug | Release ... etc. Default is NONE. So you set that to 'Release'. Then later there is a question about what CXX flags the compiler should use when making a 'Release' build. Default is already '-O3 -DNDEBUG'.I just changed this to '-O3 -march-tbird-athlon' to suit my machine. That's it!

Thank you for the hint, this "cmake -i" configuration process works very nice for me but does not improve the framerates. I just learning about this now myself, but as I understand it, one of the questions you are asked with cmake -i . is the build type. Enter "Release" (other options are things like debug, release w/ debug info, etc.) If you answer yes to advanced options, you will be presented with many more questions. One of those advanced questions relates to "verbose" make. If you change that to TRUE (defaults to FALSE) then you can see the actual compiler command line when make is run. That is one way you can verify that the -O3 option is indeed being invoked.

I was a bit confused with this - I couldn't work out what 'the configuration' screen was, nor meant. But I sussed out CMAKE now, so for anybody else with problems. Once you have a fresh checkout, in the trunk directory (top layer of code) to build the CMAKE files, issue: cmake -i . CMAKE will now run through a lot of question and shows current values, so you can change it all to suit... very handy. Any time you need to change the build, just run the 'cmake -i .' command again (after a make clean, of course). I am now going to build an optimised OSG and try again (after my 5 fps version made me move back to PLIB).

Re: [Flightgear-devel] patch for osgViewer and statistics
Hi Tim, Just tried this patch and had a couple observations (beyond noticing that it generally works pretty well.) :-) 1. The application continuously scrolls the following message: Viewer::checkWindowStatus() - 1 I couldn't immediately see where that was coming from. 2. The numeric keypad keys do not work, so flying with keyboard controls is difficult. 3. At least on the an2, the prop animation seemed to not work. I can't imagine how this would be linked, but something seems to have broken there. 4. The lack of mouse pointer change is disconcerting to say the least. One short term idea would be to pop up a temporary window like is done when you change the zoom level? That wouldn't hurt anyway so people would know initially what mouse pointer equates to what mode ... And a side note ... compiling OSG with -O3 seemed to *really* boost my frame rates ... good trick to know. Curt.

Re: [Flightgear-devel] patch for osgViewer and statistics
Hello Tim, Mathias, This is a digest of tests i have done , (and a repeat of previous separated mails) I try to understand the big FPS differences i get when i build FG first with an old OSG library 10 april 2007, second with a recent OSG library 1.9.4 version FG was patched with Tim Moore patch OSG stats. Every components and parameters are the same on both built FG : -same computer and operating system -same FlightGear cvs source -same Nvidia parameter -same Aircraft -same airport and scenery -same FG parameter -the aircraft was in place on the runway, parking brake On. The measurement values ( average) which where given are: OSG version ---old 10-04-207-||--recent v 1.9.4 Fps---41---||---14 Event4.5---||---5.5 Update--2.5---||---3.5 Cull--6.5---||---34 Draw---10.5--||---21.5 Gpu--12---||-19.5 the following snapshots show these values OLD OSG lib http://perso.orange.fr/GRTux/OSG_older-Stat.jpg RECENT OSG lib http://perso.orange.fr/GRTux/OSG-Stat.jpg Why a so big difference ? if i look at the performance i conclude, FG likes better to be built with that one month old OSG library rather than to be built with the more recent available OSG library. You could notice, 14 fps with the new OSG lib, makes FG unusable. The 41 fps which is given with the old OSG lib look like the values we had, when the first comparative tests where done, PLIB versus OSG, for me in the same situation/condition. I can understand , the old OSG content was probably more buggy than the recent one and a lot of modifications/improvements have been done on it. I wonder if FG has followed these modifications/improvements.

Every parameter are the same than these one used for the previous test, only one diff i did built SG/FG with an older OSG 1.9.4 10-april With that one do get a very good FPS with that one ( as said on a previous topic). the snapshot is there http://perso.orange.fr/GRTux/OSG_older-Stat.jpg You can notice : => your patch gives that ugly sky (blue sky has vanished, grey takes place) It is not a problem because working nice without patch. => the cull was with the previous test 35 more or less it is now 6.5 more or less. DRAW and GPU have decreased dramatically (same Nvidia parameters, High Quality, Anti aliasing setting 4x 9tap G, Anisotropic Filtering x4, Texture sharpening ON) Regards -- Gérard - This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.

Main/fg_os*.cxx are there to handle the operating system dependent interfaces for window management/keyboard/mouse: glut and later sdl. But if the osg counterparts can fully replace those two on all platforms (maybe they are even better?), then we should probably delegate that job to osg and drop glut/sdl support altogether. I doubt we would ever have introduced the fg_os* files if plib had offered all we need. glut is a dying species, just like plib ... m. - This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.

I did add some osgViewer specific code to renderer.cxx because the details of accessing the scene root, controlling the camera, and running the rendering loop are different when using a Viewer; those are concepts that fg_os doesn't handle at all. It's possible that the osgViewer changes to renderer.cxx could be refactored a bit to be less intrusive, but I'm hoping the need for the non-osgViewer case will disappear :) In the mean time the differences between the two approaches are made obvious, which I think is good for people looking at this code.

Re: [Flightgear-devel] patch for osgViewer and statistics
Hi Tim, I took a peek at the diffs and had a couple questions. Originally the idea of the fg_os files was to have a single interface within the flightgear code so that the details could be hidden in fg_os.[ch]xx, but I see with your changes that you have a lot of OSG specific code now that has filtered up into the renderer.cxx. Is that needed or could these new changes be hidden better behind fg_os like the code originally intended? Thanks, Curt.

The osgViewer framework also allows very flexible view / camera / window configuration and multithreading options which will be useful in the future.

First of all you should have the OpenSceneGraph-Data distribution from the Downloads->SampleData page of www.openscenegraph.com, unpack it, and point the OSG_FILE_PATH environment variable at it so you get the real fonts that the Stats display needs. > How may we understand the values which are given > Event > Update > Cull > Draw > Gpu > > Are they percentage of use , or anything else ? > The numbers are time, in milliseconds. The names refer to the different steps that OSG uses to update and draw a scene: Event - All non-graphics update is done here: processing user and other input, FDM, etc. Queries against the scene graph for finding height above ground are done in this phase as part of the FDM, which is currently a big bottleneck. Update - Callbacks in the scene graph are called, basically implementing all the animations. Cull - Non-visible parts of the scene are discarded, transparent objects are sorted by depth, and all geometry is grouped to minimize OpenGL state changes. Draw - Everything is rendered using OpenGL. GPU - This statistic is available only on Nvidia hardware, I think; it shows how much time the GPU takes to execute all the OpenGL requests. It won't be much smaller than the Draw time, but it could be quite a bit larger. > The "Cull" is basically very high compared to the other values but when i > fly > over the sea (without tiles as i said in an other topic). > What is exactly the meaning of the "Cull" value ? > It's hard to assign a meaning to these times in isolation, except to note that 16 milliseconds total is the magic number that gives you a frame rate of 60hz. The large cull time indicates poor scene graph layout; possibly there's a problem with transparent objects in your beautiful cockpit :) The large draw time vs. gpu time shows that the scene and model geometry could be grouped in larger batches. > I get ThreadingModel : SingleThreaded , is it right ? > Yes; I've forced all the OSG operations into one thread to start with.

Gpu is the time used by the gpu only. Event+update+cull+draw+a bit of gpu gives your total frame time. The cull time is enormous but this should be better soon. But your draw time is astronomous too. I can not comment on that with only a screen shot. What we need now is the number of drawelement calls, I'm sure Time will add this ;) Harald. - This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.

How may we understand the values which are given Event Update Cull Draw Gpu Are they percentage of use , or anything else ? The "Cull" is basically very high compared to the other values but when i fly over the sea (without tiles as i said in an other topic). What is exactly the meaning of the "Cull" value ?
